VW Vanagon fuel pumps are very sensitive to running dry. The fuel they pump keeps them cool. As soon as the key is turned to the "on" position, the pump (just below your sliding door) should buzz. If not, replace it.

And replace the filter, while you are at it. That is if you don't recall the last time it was replaced.

A Vise-Grips, with padding, upstream from the pump and filter makes the job much less messy.

Good luck, and kind regards,
Ric

Hello,
in addition to the "buzz" test, that is if it buzzes but it still won't start, try some of the basic tests.
Having "The Book" will be very useful.
For fuel:
- try a fuel pressure test, if you have a pressure gauge,
  • test the injector spray pattern (simply detach
the injector pair on one side at a time,
get an appropriate pan/cup and have someone
try to start it. You should see a cone-shaped spray)
For spark:
- remove one wire at a time and insert a good
spark plug. Touch the engine ground with the
spark plug and have someone crank it.
- test also spark timing

Best of luck, let us know how you do,
Claudio
